Beschreibung
Zusammenfassung:	A sound generating apparatus comprises a first cavity 110, a second cavity 120 and an electromechanical transducer 100 that emits sound waves into the first cavity and the second cavity. A third cavity 130 is connected to both the first and second cavities via a first passage 115 and a second passage 125. Sound waves of the first cavity 110 pass to the third cavity 130, via the first cavity and the second passage serves as a passage for sound waves to the third cavity 130. Passed through sound waves are mixed in the third cavity 130 and are allowed for passing through one or several outlets 150 for emitting sound into an exterior of the apparatus. A mobile electric device is provided having integrated the above described sound generating apparatus and a system for generating sound of improved quality being based on components integrated in the sound generating apparatus.
